FIREPROOF CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 632,523, datedSeptember 5, 1899.

Application filed April 27, 1899. Seria1No.7l4r670| (N0 lIlOdBl-l To allwhom t may concern:

Be it known that I, GODFREY FUGMAN, a resident of Cleveland, county ofCuyahoga, and State of Ohio, have invented certain new and usefulImprovements in FireproofConstruction; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

My invention relates to improvements in reproof constructionfoi-buildings, and more especially to partitions or walls for buildings.

The primary object of the invention is to provide an improved metallicbody for a partition, a body that is strong and durable and inexpensivein construction, that requires little labor in its erection, that doesnot require studding, posts, or uprights for supporting it, and thatrequires comparatively little plaster in plastering the body and forms avery adequate support for the plaster.

With this object in View my invention consists in certain features ofconstruction hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a top plan of my improved bodyfor a portion of a partition or wall, and a portion of the body isplastered upon opposite sides. Fig. IIv

is a side elevation of a portion of the body. Fig. III is a verticalsection on line III III, Fig. I, looking in the direction of the arrow.Fig. IV shows a portion of the metallic sheet or blank employed inmaking the body.

My improved metallic body that, as already indicated, is more especiallydesigned for use in constructing partitions or walls for buildings ismade from a metallic sheet. (Shown in Fig. IV.) This sheet is providedwith any suitable number of rows of preferably parallel slits ct,extending transversely of the respective row. Adjacent rows of slits arearranged in very close proximity to each other, so as to leave a verynarrow plain or unslitted portion d between adjacent rows of slits. Theportion of the sheet between adjacent slits of each row of slits is bentlaterally in any approved manner and semicircularly or approximatelysemicircularly, so'as to form a semicircular or approximatelysemicircular wing, andthe portions between the slits of each row ofslits are bent preferably alter- I nately in opposite directions, so asform two rows of wings a2 and a3 upon opposite sides, respectively, ofthe bodyand so that the wings of each of the said rows shall alternatewith the wings of the other row. The slits of each row of slits arearranged, preferably, only a short distance apart, so as to result inthe formation of a partition or wall having lateral wings or arches thatare narrow in a vertical direction.

The drawings show a full-sized body suitable for the formation of acomparatively thin partition. If a thicker partition is required, theslits should be made longer and a larger blank should be employed, sothat the wings or arches shall be wider from end to end. I would remarkalso that the wings of each row of wings upon each side of the body arearranged, preferably, so as toV alternate with the wings of the adjacentrow or rows of wings upon the same side' of the body.

In my improved body it will be observed that each wing in each row ofwings upon each side of the body is contiguous endwise with a wing orwings upon the opposite side of the body and that there is no break oroffset between the said contiguous wings. Any break or odset between thesaid wings would materially weaken the partition, and the greatimportance of having each wing upon each side of the body terminateendwise directly in a wing or wings upon the opposite side of the bodyis therefore obvious.. 'The narrow unslitted portions a between the rowsof slits in the blank are, when the winged body is formed, out of theiroriginal plane and are arranged at right angles or approximately atright angles to the said original plane, as shown very clearly in Fig.III, and this is an important factor in strengthening the body. I haveobserved also that the'circular form of the wings is remarkable as toits capacity for strength and rigidity.

A portion of the body illustrated in Fig. I is plastered at b uponopposite sides, and it will be observed that the vertically-narrow wingsof my improved body form a very adequate support for the plaster. Thecircular form of the wings reduces the plastering-receiving spacesbetween adjacent` rows of IOO wings upon each side of the body to aminimum", and any construction that will unnecessarily enlarge the saidspaces will result in a Waste of plaster. i

In erecting my improved partition or Wall no studding, posts, or uprightsupports are needed. The body is of course fastened in any approvedmanner at the top and bottom to the oors or floor-supports above andbelow, respectively.

It is obvious that the unslitted portions a. a at opposite ends,respectively, of a wing are by the peculiar formation and arrangement ofthe wings' hereinbefore described turned in opposite directions,respectively, so that the metallic connection between adjacent ends ofadjacent reversely-arranged wings may-be still further reduced or almosteliminated by a resulting elongation ot' the slits between which thesaid wings are formed; but this reduction of the integralism between thesaid wings does not reduce the strength vot the body that instead ismaterially improved in strength by the elimination of a break or olsetbetween the said wings.

What I claim is- 1. A body for partitions or walls, made from a metallicsheet that is provided with slightly-separated rows of parallel slitsarranged a short distance apart, and has the portions between the slitsbent laterally into a semicircular or approximately semicircular form,substantially as and for the purpose' set forth.

2. A metallic body for partitions or Walls provided withslightly-separated rows of laterally-projecting wings formed a shortdistance apart upon each side of the body and having wings in each rowof wings arranged alternately and having the wings in each row of wingsalternating with wings of the adja cent row or rows of wings upon thesame side of the body, substantially as shown, for the purposespecified.

3. A metallic body of the character indicated having upright rows oflaterally-projecting wings or members upon each side of the body, thewings of each row alternating with the wings of the opposite row andalternating with the wings of the adjacent row or rows upon the sameside of the body, and each wing of each row of wings terminating endwisein a wing or wings upon the bodys opposite side without the formation ofan'y break or offset between the said wings, suba stantially as shown,for the purpose specified.

4. A metallic body of the character indi cated, made from a metallicsheet having slightly-separated rows of slits ct arranged transverselyof the respective row, which sheet has the portions between the slits ofeach row of slits bent orbowed laterally so'as to form two rows of wingsa2 and a3 arranged upon opposite sides, respectively, of the body, thewings of each row of wings alternating with the wings of the oppositerow and alternating with the wings of the adjacent row or rows of wingsupon the same side of the body, and the unslitted portions a between therows of wings being bent or turned into a position at right angles orapproximately at right angles to the plane of the original sheet,substantially as shown, for the purpose specified.

Signed by me at Cleveland, Ohio, this 21st day of April, 1899.
